Answer:
Democratic government vs. communism
Step-by-step explanation:

Between 1900 to 1949 most countries such as China and the Soviet states were advancing the course of communism.
The US and other democratic governments battled the communism ideals. China won a war between them and opponents of communism in October 1, 1949. The soviet union manufactured and detonated its nuclear weapons in competition with the United States. There was a big conflict between these two ideologies within this period.
